204 PSYCHE (Oct.— Dec. 



in the specimens of S. bridweUi but is seen in all the specimens of S. flavipes 

 (nine) accessible to me. Whether this hook-like vein is a universal character of 

 S. flavipes I cannot say, but I do not find it mentioned in any of the descriptions 

 of this insect. (See Figs, i and 3.) 



It is probable that the name Sphex flavipes Sm. will need to be replaced by 

 another, as this name was used by Fabricius much earlier for a different insect, 

 which brings the present S. flavipes under the last portion of Canon XXXIIl of 

 the A. O. U. Code.
